CESD5V0K5 from Changjing, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | ESD-protected line 1 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A); pin 1 is marked by the solid dot. |
| 2 | GND | power_in | Common ground/anode node of all five protection diodes; ESD ratings are specified per channel from I/O to GND. |
| 3 | I/O2 | passive | ESD-protected line 2 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A). |
| 4 | I/O3 | passive | ESD-protected line 3 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A). |
| 5 | I/O4 | passive | ESD-protected line 4 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A). |
| 6 | I/O5 | passive | ESD-protected line 5 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A). |
